  1. Radar Level transmitters Set Up, Working Principle, Types & Industrial Applications

  2. Introduction • Radar Level Transmitters are used is different applications for fluid measurement. The function of these transmitters are based electromagnetic waves at a range of 10GHz. • There are two types of Radar Level Transmitters: • Non-Contact Systems • Contact Systems

  3. How to Setup Radar Level Transmitter? • Setting up the Radar Level Transmitters is rather easy. There are three main components that are required for setting up these Transmitters: • Solid-State Oscillator • A Radar Antenna • Receiver and Signal Processor System • Along with these components, TTS offers Setup Wizard with advanced systems. It acts as a software interface to the transmitter operation.

  4. Working Principle of Radar level transmitters • The working principle is a function of Time Domain Reflectometry (TDR), which is also known as the Time of Flight (TOF) radar measuring principle. • Following is the step-by-step explanation of Radar Level Detector’s working principle: • Firstly, the solid-state oscillator is installed in radar level sensor setup oscillates electromagnetic waves to the fluid surface. • After the electromagnetic waves hit the fluid surface, it reflects a pulsating signal to the radar antenna. • The time to level calculation is performed by the signal processor.

  5. Different Types of Technologies In Radar Level Transmitters • Guided Wave Radar Level Transmitters – It is a contact type of transmitter, where TDR probes are immersed in dry or bulk media. TDR Probes can: • Detect the advancing motion of the electromagnetic waves • It get rids of obstacles in between the path of waves. • These probes are highly immune to high temperature, pressure and environmental damage. • This technology is suitable for harsh environment and is highly compatible with high-end industrial applications as it require zero maintenance. TDR technology is used in the guided wave radar level sensors and guided wave radar level transmitters.

  6. Different Types of Technologies In Radar Level Transmitters • Frequency Modulated Continuous Wave (FMCW) Transmitters – Radar Antenna’s are used in transmitters which are working on FMCW technology. • The radar antenna emits a signal and the receiver catches it within a specific time.  • Transmitters with FMCW Technology are non-contact systems. • This technology emits high-frequency continuous signals with gradually increasing frequency. • Due to frequency sweep, continuous measurement is possible in this technology.

  7. Applications of Radar Level Transmitters • Radar Level Transmitters are used in critical engineering environments. The industrial applications are as follows: • Mining Industry • Boiler Engineering • Aeronautics Industry • Paper and Pulp Industry • Bore Digging Technology

  8. Applications of Radar Level Transmitters • Radar Level Transmitters are used in critical engineering environments. The industrial applications are as follows: • Mining Industry • Boiler Engineering • Aeronautics Industry • Paper and Pulp Industry • Bore Digging Technology

  9. Conclusion: • Now that we have understood the set up, working principle, types and applications of Radar Level Transmitters, it becomes important to make the correct choice by sourcing these devices from reliable supplier. • TTS offers level measurement sensors from leading manufacturers like Emerson, Foxboro, Honeywell and many others.
